MMO kit with server?

#1 There isn't any current MMO kit.

A map of that size is entirely possible, and 512 players is doable, though it'd require you to go through the networking and streamline out stuff you don't need to keep the network traffic as lean as possible.

The 2 main things would be getting your server architecture set up, and making all the content for it. Content isn't individually a huge issue, but there's so much of it you need.

Still, if you're not shooting for thousands of players on a server, it becomes much more reasonable a target compared to attempting to making the next WoW.

I'd say for starters, what kind of gameplay setup were you looking at? Turn-based? Realtime? How fast data has to arrive to the server and clients makes a big impact on the backend architecture requirements.

#2 I think you can start using the RPG Engine Kit you can download a demo or buy it from here: gumroad.com/12catblack and them start your way for a MMO

More info about RPG Engine Kit: www.garagegames.com/community/blogs/view/22664 and www.garagegames.com/community/blogs/view/22599

I'm not sure but I think support a new version of Torque3D

Or you can start using MyRPG Master, is the same Torque3D with some editors and art assets: www.garagegames.com/community/blogs/view/22941 but you need to buy it from steam store.steampowered.com/app/329890. I do not know how updated this is with the current Torque3D.

BTW FYI like Jeff Raab said currently not exist a MMO Kit but there is an old MMO Kit www.garagegames.com/community/blog/view/13391/ - www.garagegames.com/community/blog/view/13051 but is long gone, maybe you can search for it

Or you can use an diferent engine like this: www.worldforge.org - sourceforge.net/projects/worldforge/ or you can use sourceforge.net/projects/multiverse3d for 2D sourceforge.net/projects/mmorpgmaker
